LINOTYPE-MACHINE OR THE LIKE.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Application fled April 20, 1914. Serial No. 833,162.

To all whom it may concern:

Be it known that 1, JOHN B. SHUFELDT, Jr.,- of New York, in the countv of Bronx, and in the State of New York, have invented a certain new and useful Improvement in Linoty e-lriachines or the like. and do heredeclare that the following is a full, clear, and exact description thereof.

My invention relates to an improvement in linotype machines or the like and has for object to provide a simplified keyboard {if such machines.

In linotype machines in commercial use, a separate key must .be pressed for upper case and for lower case letters of the same kind,

the pressing of each key releasing a single matrix from the magazine, from whence it is carried by a matrix belt to an assembler. This necessitates alarge keyboard which is complicated and difficult to learn, and which it is almost impossible to operate by the touch system on account of its size. No successtul or practical mechanism for releasing the matrices by a simpler keyboard has been devised, to my knowledge, previous to my invention' The embodiment of my invention disclosed herein releases the desired matrix accurately and surely under all conditions of operation, and may be adapted readily to linotype on similar machines already in use, with comparatively simple adjustinents thereof.

Referring to the drawings, Figure 1 is a side elevation: and Fig. 2 is a diagram of one method of wiring, closed circuits being indicated in full lines.

Similar reference characters refer to similar parts throughout the drawings.

Although invention has been shown applied to a doublemagazine linotype, commonly called a double-decker, it is not to be limited to this type of machine, which was chosen to illustrate my invention solely because it is possible in this type to show a side view of two separate magazine channels conveniently and without confusion. My invention is applicable to all kinds of linotype or similar machines and operates with equal certainty and precision with all dcsigns and types.

The magazine, the matrix, and the ma trix-escapement for holding and releasing the matrix, may be the same as in present types of commercial linotype or similar machines, but may, however, be changed or modified when used with my invention, to

meet varied conditions or improvements in such machines. The ordinary matrix-escapement mechanism illustrated consists of two vertical pawls l and which prof t through the under side the maganine and engage the ears or" the matrices. The pawls for each matrix are seated. in a verge 3 which is pivotedat its center so that when one pawl is raised the other is lowered. The verge is operated by the keyrod i which hooks into the verge in well known manner as shown.

The spring 5, mounted on keyrod t between a head on the end thereof and a guide In the embodiment chosen for illustration, 4

instead of connecting the operating key to thekeyrod by mechanical means as in the present type of linotype or similar machines, I provide electrical connecting means consisting of an electrical circuit containing a source of electrical power, operating keys to close'the circuits, and magnets or solenoids adapted to act upon the kcyrods and thereby operate the matrix escapement. A magnet is provided for each keyrod, and they may be arranged in any position or relation to secure economy of space. For convenience of illustration. magnet 6 will be considered as controlling the matrix escapement of a matrix bearing the letter a, and the magnet 6 as controlling the matrix escapement of letter A. vention illustrated, one ke Y 7 on the keyboard controls both these magnets. When said key 7 is pressed alone it releases a matrix bearing the letter a, but when pressed in connection with master-key 8 it releases the matrix bearing the letter A. Each key on the keyboard in like manner will a matrix bearing the, In the embodiment of my in control two matrices, releasing one matrix when pressed alone, and releasing the other matrix, when pressed in connection with the single master key 8.

5 Referring to Fig. 2, full lines indicate a circuit including magnet 6, a source of electrical power indicated at9, and an operating-key 7 adapted to close the circuit when p13S$Qd; The closing of the circuit energiize s magnet 6 WlllCh in the illustration will cause the release of a matrix bearing the letter a. When key 8 is pressed in connection with key 7, the circuit through magnet 6 is broken at 10 and completed at 11, thereby closing the circuit indicated b dot and dash lines (which normally is open and energizing magnet 6 which, in the illustration, will cause the release of a matrix bearing'the letter A. a

' In order that the touch of the machine maybe adjusted to suit the operator, adjusting screws 12 and 13 are provided as shown in Fig. 1, which controls the distance which each key must move when pressed to control d the circuits in the manner above indicated.

It isevide'nt that other embodiments of my invention will be apparent to those skilled in the art without departing from the scope thereof, or from the scope of my claims, it being my intent to provide a simple and efi'ective device whereby each key on the board controls two matrices, one matrix being released when the key is operated alone and the other matrix being released when the key is operated in conjunction with the master key. h
